Two large enterprise AEM implementations were presented and compared. Anshul Chhabra from Symantec presented their implementation handling 3.3 billion requests per month. Anil Kalbag from Cisco presented their implementation handling 375 million monthly page views. Both implementations utilized multiple data centers for high availability and disaster recovery. Key architecture decisions around virtual/physical infrastructure, storage, caching, and multi-tenancy were discussed and compared between the two organizations.

• Finite number of Instances – with Governance
• New instance should be created only when:
– Independent branding and experience
– Independent Dev teams and stakeholders – with
totally different integrations
– Totally different operational SLAs required
– Example Symantec/Norton

Migration Strategy
12
• Technologies before AEM: Teamsite, Drupal
• AEM adopted three years ago
• Major web presence on AEM
– Long tail of migrations continue to this day
• Two options for migrations
– Assisted Migrations (scripted, automated)
– User driven (new platform for new content + retire older content)

AEM Architecture Anti Patterns
30
• Over Customization
• Everything is a nail – when AEM is the hammer
• AEM as a Façade
• AEM as THE Application Engine
• Taking every “sold” feature on its face value
• AEM – Target integration
• Continuing to use AEM classic UI over touch
• Not planning for continued investment in AEM (and other Adobe) Products &
resources
• Includes investment in a tight well organized team
• Investment of time in building a good relationship in Adobe & community

31. © 2016 Adobe Systems Incorporated. All Rights Reserved. Adobe Confidential.
AEM in the cloud
31
• Most installations so far are on prem – or not completely cloud native.
• Future – looks different – more and more push to Cloud.
• Multiple options going forward
• AEM Managed Services (AWS MarketPlace)
• Azure Virtual Machine (BYOL) – on windows
• Rackspace – complete with full suggested deployment architectures
• Need Adobe Product to evolve more also:
• More Cloud Native offerings
• Support for MicroServices & Continuous Integration& Delivery
• Better Support for Multi Tenancy in same instance

Wishlist from Adobe
32
• Improved Integrations – eg: Target, Segments (Audience Mgr), eCommerce
• Better Support and penetration in Cloud
• More Cloud Native offerings
• Support for MicroServices & Continuous Integration& Delivery
• Better Support for Multi Tenancy in same instance
• More robust and scalable repository
• Improved support for Active Passive Mode, Backups, Maintenance activities
• Improved content transfer capability from Prod to Non-Prod
